I heard that especially large plants like amazon sword can make a mess of
the UGF's with root entanglements, etc... how hard are they to transplant
(by cutting it off of filter if necessary), for something like upgrading to
a larger tank, etc? or is that too harsh a pruning to survive?

Sigh. Again with the UGF-bashing. I have half-a-dozen tanks and have
been
keeping planted tanks for over twenty-five years. Practically every
single
one has or has had an undergravel filter. There is no problem with using
UGF's.
